But I agree, most of the time UM+ seems to be a good option.

I've used UM+ in Austria and had no problems...

One of the problems is that for some reason it seems some carriers try to block access to UM or UM+....the solution is to manually select a roaming carrier...I've had cases say in France where I couldn't get it to work with Orange FR but it worked flawlessly with SFR.

Just out of curiosity, did you try to manually set the roaming partner?
